Method Detail

stringToExpression

public static Expression stringToExpression(java.lang.String expression,
                                            Model model,
                                            ExpressionParseListener parseListener)
                                     throws ExceptionHugin

Converts a string to an Expression.

Parameters:

expression - the String to be parsed.

model - the Model to which the expression belongs.

parseListener - the ExpressionParseListener that handles parse errors occuring during the parsing of 'expression'.

Returns:

If the parsing completes successfully, an Expression object corresponding to 'expression' is returned.

stringToExpression

public static Expression stringToExpression(java.lang.String expression,
                                            NetworkModel network,
                                            ExpressionParseListener parseListener)
                                     throws ExceptionHugin

Deprecated. Replaced by stringToExpression(String, Model, ExpressionParseListener).

isCompositeExpression

                              throws ExceptionObjectNotAlive

Tests if the the expression is a CompositeExpression.

Returns:

A boolean.

isConstantExpression

public boolean isConstantExpression()
                             throws ExceptionObjectNotAlive

Returns:

A boolean.

isNodeExpression

public boolean isNodeExpression()
                         throws ExceptionObjectNotAlive

Tests if the the expression is a NodeExpression.

Returns:

A boolean.

expressionToString

public java.lang.String expressionToString()
                                    throws ExceptionObjectNotAlive,
                                           ExceptionHugin
